Description

Technical Field

[0001] This utility model relates to the field of microwave oven technology and equipment, and in particular to a multifunctional drawer-type microwave oven. Background Technology

[0002] Currently, most drawer microwave ovens on the market are limited to single microwave heating or a basic microwave + grilling combination (quartz tube / light wave heating). This low level of integration makes it difficult to meet the growing demand from modern consumers for multifunctional, high-efficiency cooking (such as air frying, professional baking, fermentation, and defrosting). Even those few products that integrate convection or air frying functions often have significantly larger overall dimensions (especially height and depth). This large-scale design makes them unsuitable for use in standard-sized cabinets installed earlier. When upgrading or replacing older models, users face the dilemma of not being able to install them in their original locations, often requiring expensive cabinet modifications or complete replacements, greatly increasing the cost and complexity of the upgrade.

[0003] Therefore, there is an urgent need to develop multifunctional drawer-type cooking appliances that integrate microwave, grill, hot air convection, and air fry functions while maintaining or approaching the standard size of traditional drawer-type microwave ovens. This would effectively solve the functional limitations and space adaptability issues of existing products and meet consumers' needs for convenient upgrades and diversified cooking experiences. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a multi-functional drawer-type microwave oven. This invention saves space in terms of height and depth, so that the multi-functional drawer microwave oven can also be installed in a cabinet with a single microwave drawer.

[0005] To achieve the above objectives, this utility model provides a multifunctional drawer-type microwave oven, including a drawer door assembly, a cavity assembly, a hot air assembly, a microwave generator, a control assembly, a drawer movement mechanism, and a shell for enclosing the above-mentioned components.

[0006] The cavity assembly is installed inside the outer shell. The top of the cavity assembly is provided with a top plate, and a recessed first mounting cavity is provided on the top plate. The first mounting cavity has a first ventilation opening that communicates with the interior of the cavity assembly. The lower part of the cavity assembly forms a second mounting cavity with the inner wall of the outer shell, and the rear of the cavity assembly forms a third mounting cavity with the inner wall of the outer shell.

[0007] The hot air assembly is disposed on the first mounting cavity;

[0008] The microwave generator includes a stirring motor disposed below the cavity assembly;

[0009] The drawer door assembly is movably disposed on the front side of the housing to seal the cavity assembly;

[0010] The drawer motion mechanism is installed in the second mounting cavity and encloses the stirring motor. The drawer motion mechanism is connected to the drawer door assembly to realize the opening and closing of the drawer door assembly.

[0011] The control component is located inside the housing and is used to control the operation of each component.

[0012] Furthermore, the drawer motion mechanism includes a first mounting plate and a drive wheel assembly, a driven wheel assembly, a first transmission toothed belt, and a drawer drive motor fixed to the first mounting plate. The first mounting plate is fixed below the cavity assembly, and a first protrusion is provided in the middle of the first mounting plate. The other side of the first protrusion encloses the stirring motor. The first transmission toothed belt is linked to both the drive wheel assembly and the driven wheel assembly, and the drawer drive motor is connected to the drive wheel assembly. The first mounting plate allows for the installation of all components of the motion mechanism, while the first protrusion in the middle encloses the stirring motor, thus improving overall space utilization.

[0013] Furthermore, the drive wheel assembly includes a drive wheel seat, a drive wheel, a drive wheel, a first transmission shaft, two sets of first bearings, and two sets of first bearing seats. The drive wheel seat is fixed to the first mounting plate, and the two sets of first bearing seats are respectively fixed to the front and rear sides of the drive wheel seat. The two sets of first bearings are respectively engaged with the two sets of first bearing seats. The first transmission shaft passes sequentially through the first first bearing, the drive wheel, and the second first bearing and connects to the drive wheel. The drive wheel is linked to the drawer drive motor via a second transmission belt. This modular design of the drive wheel assembly effectively improves installation efficiency. Simultaneously, the symmetrical support structure formed by the front and rear sets of first bearing seats and bearings effectively enhances the radial load capacity of the transmission shaft. Dual-point positioning ensures the coaxial accuracy of the transmission shaft and reduces eccentric vibration.

[0014] Furthermore, the driven wheel assembly includes a driven wheel mounting base, a driven wheel, a second drive shaft, and a driven wheel fixing plate. The driven wheel mounting base and the driven wheel fixing plate are fixed together perpendicularly to form a first shaft hole. The second drive shaft is mounted on this first shaft hole and connected to the driven wheel. Specifically, both the driven wheel mounting base and the driven wheel fixing plate are frame structures with openings on both sides. A first insertion hole and a second insertion hole are respectively provided on the driven wheel mounting base and the driven wheel fixing plate. The driven wheel mounting base and the driven wheel fixing plate are fixed together perpendicularly, so that the first insertion hole and the second insertion hole are perpendicularly overlapped to form the first shaft hole. The perpendicularly intersecting driven wheel mounting base and fixing plate (angle 90°±0.5°) form a spatial rectangular coordinate system positioning reference, ensuring that the coaxiality error of the second drive shaft is ≤0.1mm.

[0015] Furthermore, the drawer door assembly includes a drawer door and drawer rails. The drawer rails are fixed to both sides of the cavity assembly, and both sides of the drawer door are connected to the drawer rails. A first connector is provided at the lower end of the drawer door, extending into the second mounting cavity. A first connecting block is connected to the end of the first connector, and the first connecting block is connected to the first transmission toothed belt. The drawer door is moved by pulling or pushing it from the bottom center using the first connector. Combined with the dual guide rails on both sides, synchronous left and right movement can be achieved, improving the stability of the drawer door's opening and closing. Simultaneously, placing the first connector at the bottom allows for efficient use of vertical space in conjunction with the drawer door movement assembly.

[0016] Furthermore, an upwardly protruding mounting boss is formed in the middle of the top plate, and the center of the mounting boss is recessed towards the cavity assembly to form the aforementioned first mounting cavity. The mounting boss is designed to install a hot air shroud, forming a recessed first mounting cavity, which allows the hot air assembly to be installed within the first mounting cavity. This ensures that the mounting surface of the hot air assembly is lower than the plane, thereby allowing the hot air assembly to be placed in the top cover without forming or reducing the formation of protrusions, thus improving space utilization.

[0017] Furthermore, the hot air assembly includes a hot air motor, a heating element, a hot air inner cover, a hot air outer cover, and hot air fan blades. The hot air inner cover is fixedly connected to the first mounting cavity. The hot air outer cover encloses the hot air inner cover and is mounted on the mounting boss. The hot air motor is detachably connected to the top of the hot air outer cover. The hot air fan blades are placed inside the hot air inner cover and are linked to the hot air motor through a connecting shaft. The heating element is mounted on the mounting boss and passes through the first mounting plate, positioned at the upper end of the cavity assembly.

[0018] Furthermore, the cavity assembly is formed by splicing together a front panel, a U-shaped frame, a top panel, and a rear panel. A second ventilation opening is provided on the rear panel, and a third ventilation opening is provided on the top panel. The second and third ventilation openings allow the first and second mounting cavities to communicate, which is beneficial for heat dissipation. The U-shaped frame can be used to install drawer slides.

[0019] Furthermore, the system also includes an air duct assembly comprising an air duct base mounted on the second mounting cavity, air duct fan blades mounted on the air duct base, and an air duct motor, wherein the air duct base is located adjacent to the second ventilation opening. The air duct assembly facilitates airflow between the first and second mounting cavities, promoting heat dissipation.

[0020] Furthermore, the control components include a control board, a power board, a filter board, and a touch panel that are electrically connected to each other. The touch panel is located at the front end of the top plate, and the power board and the filter board are fixed to the inside of the top plate.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. This invention adds a top hot air assembly to the single-drawer microwave oven, which can integrate multiple functions such as microwave, grill, hot air, and air fry, making it a multi-functional appliance. This effectively avoids the need for users to purchase multiple single-function appliances and can effectively free up kitchen space occupied by multiple appliances.

[0023] 2. Addressing the common issues of increased size (especially height or depth) and difficulty in fitting existing standard kitchen cabinets with hot air functions, this invention solves the problem by lowering the top panel structure to form a first mounting cavity. This ensures the hot air assembly mounting surface is lower than the top surface of the main body, achieving a recessed cavity design. Furthermore, by arranging the drawer's movement mechanism to completely enclose the stirring motor's vertical projection, the entire hot air assembly can be accommodated without significant or minimal protrusion (micro-bulge) on the top cover, while minimizing the space occupied by the movement mechanism. This achieves overall compatibility (especially height) with basic single-function drawer microwave ovens, allowing for direct, in-situ installation in existing standard kitchen cabinet spaces, eliminating the additional costs and hassles associated with cabinet modifications for equipment upgrades.

[0024] 3. This utility model simplifies the structure of the drawer movement mechanism, which not only reduces the complexity of the mechanism, but also realizes the modular construction of the components, making the mechanism highly detachable and replaceable. If maintenance or replacement is required in the later use of the equipment, the faulty module can be quickly located, disassembled and replaced, which significantly reduces the difficulty of maintenance and saves maintenance costs.

[0045] like Figure 3 and Figure 5 As shown, a recessed first mounting cavity 232 is provided on the top plate 23. Specifically, an upwardly protruding mounting boss 233 is formed in the middle of the top plate 23. The center of the mounting boss 233 is recessed towards the cavity assembly 2 to form the aforementioned first mounting cavity 232. A recessed stepped portion 234 is formed between the first mounting cavity 232 and the mounting boss 233. The stepped portion 234 is flush with the end face of the top plate 23. The recess of the first mounting cavity 232 makes its top surface flush with the end face of the stepped portion 234, that is, the end face of the first mounting cavity 232 is lower than the end face of the top plate 23. This creates a sufficient installation area between the top plate 23 and the upper cover plate 73 for installing the hot air assembly 3. To facilitate the connection between the hot air assembly 3 and the cavity assembly 2, a first ventilation port 235 communicating with the interior of the cavity assembly 2 is provided on the first installation cavity 232.

Figure 2 and Figure 3 As shown, the air duct assembly includes an air duct base 81 disposed on the second mounting cavity 25, an air duct fan blade 82 disposed on the air duct base 81, and an air duct motor 83. The position of the air duct base 81 is adjacent to the second ventilation port 241, thus forming a heat dissipation air duct, which can realize the airflow and heat dissipation of the two sides, the rear side and the top of the cavity assembly 2.

[0049] The drawer door assembly 1 is movably disposed on the front side of the outer casing 7 for sealing the cavity assembly 2 and conveying food. The drawer door assembly 1 includes a drawer door 11 and a drawer guide rail 12. The drawer guide rail 12 is fixed to both sides of the cavity assembly 2.

The first connector 13 passes through this through hole and enters the second mounting cavity 25. A first connecting block 14 is connected to the end of the first connector 13, and the first connecting block 14 is connected to the first transmission toothed belt 64. The first connecting block 14 is a flat plate and is placed below the first protrusion 611. This does not interfere with the operation of the stirring motor 41 located at the other end of the first protrusion 611, improving space utilization. Figure 9 As shown, the drive wheel assembly 62 includes a drive wheel seat 621, a drive wheel 622, a drive wheel 623, a first transmission shaft 624, two sets of first bearings 625, a drive wheel baffle 628, and two sets of first bearing seats 626.

The two sets of first bearings 625 are respectively snapped onto the two sets of first bearing seats 626. The drive wheel baffle 628 is a frame structure with an opening on one side. The drive wheel baffle 628 is used to enclose the assembled first bearing seats 626, first bearings 625, and drive wheel seat. 621 and drive wheel 622 can protect the two sets of first bearings 625, preventing sand or other pollutants from entering the two sets of first bearings 625 and interfering with their normal operation. The drive wheel baffle 628 is provided with a wheel baffle through hole 6281 for the first drive shaft 624 to pass through. The first drive shaft 624 passes through one side of the drive wheel baffle 628, the first first bearing 625, the drive wheel 623, the second first bearing 625 and the other side of the drive wheel baffle 628 in sequence and then connects to the drive wheel 622. The drive wheel 622 is linked to the drawer drive motor 65 through the provided second drive belt 627.

[0052] like Figure 10As shown, the driven wheel assembly 63 includes a driven wheel mounting base 631, a driven wheel 632, a second drive shaft 633, and a driven wheel fixing plate 634. Both the driven wheel mounting base 631 and the driven wheel fixing plate 634 are frame structures with openings on both sides. A first insertion hole 6311 and a second insertion hole 6341 are respectively provided on the driven wheel mounting base 631 and the driven wheel fixing plate 634.

In this embodiment, the first insertion hole 6311 is vertically arranged on the driven wheel mounting base 631, and the second insertion hole 6341 is horizontally arranged on the driven wheel fixing plate 634, so that the first insertion hole 6311 and the second insertion hole 6341 are perpendicularly superimposed to form a first shaft hole 635. The second drive shaft 633 is installed in the first shaft hole 635 and connected to the driven wheel 632. It should be noted that in some other embodiments, the first insertion hole 6311 and the second insertion hole 6341 are... The orientation of 6341 can be changed according to different environments. The orientation of the first insertion hole 6311 and the second insertion hole 6341 can be various, not necessarily horizontal or vertical. It is only necessary to ensure that the closed ends of the first insertion hole 6311 and the second insertion hole 6341 can overlap when the driven wheel mounting base 631 and the driven wheel fixing plate 634 are spliced. The vertical orientation of the first insertion hole 6311 and the second insertion hole 6341 is shown as the optimal mode of this utility model. Other orientations are also within the protection scope of this utility model.
